SPECIFICATION forming part of Letters Patent No. 532,548, dated January15,1895.

Applioatioufiled March 12, 1894.. Serial No. 503,283. (No model.)

.To all whom it may concern:

Be it known that 1, WILLIAM H. GOLDING, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Printing- Presses, of which thefollowing is aspecification.

This invention relates to that class of printing presses employing areciprocating platen, and consists in a number of improvementscalculated to increase the efficiency of the press and facilitate itsmanipulation, all of which are fully described hereinafter andpointedout in the claims appended.

Reference is to be had to the annexed drawings and totheletters markedthereon, forming a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Figure 1 shows a side elevation of the press. Fig. 2 shows a sectional-view on an enlarged scale of the platen-operating means. Figs. 3 and 4show the upper portion of the press in side elevation on an enlargedscale as viewed from the opposite side to that seen in Fig. 1. Fig. 5shows a cross-section of an ink-receptacle and rollers. Fig, 6 shows thesame parts in side elevation partially broken away. Fig. 7 shows adetail of registering or counting means. Fig. 8 shows a detail of partof a work-table and appurtenances. Figs. 9, 10 and 11 show sectionalviews illustrative of means for holding aswiveled leaf of said table indifferent positions. Fig. 12 shows a detail of means for holding thethrow-off mechanism in one adjustment. Fig. 13 shows a per-. spective ofthe supporting base of the machine, and a'belt-shiftingandbrake-applying mechanism. Fig. 14' shows a rear elevation of the pressrepresented as broken out at one art. p The-upright sides, a, of themachine have pivotally connected with their upperends arms, a which areprovided with set-screws, (L to bear on lugs, a on said upright sidesand support the arms. An ink-transferring roller, a, is-supported bysaid arms as is also an ink-receptacle, a which is pivotally connectedwith the arms and provided with an inclined bottom, 0., whose edgeextends along the roller, a, and a hinged lid, a". The

amount of space allowed for exit of ink be tween the edge of saidinclined bottom and the surface of the roller is regulated by means ofscrews a and a entered through an ear on the ink-receptacle, and onebearing against the arm a, while the other enters a threaded holetherein. A set screw, a entered through a cross-bar, a extending betweendepending portions of the sides of the receptacle, and bearing againstthe under side of the inclined bottom, 0.", provides means for truingsaid bottom with respect to the roller, 2'. e., making its edge parallelwith the roller so there will be a uniform distributionof ink thereon.

There maybe more than one of these screws a The usual yieldinglysupported distributing rollers, 12, are arranged to travel over theintermittently moving disk, 0, and in the construction here shown thesides, a, are formed with raised edges, b, near the upper end, and theupper roller, 1), is designed to run up on these edges, 19', and beraised thereby out of contact with the disk, 0, and into contact withthe roller, a so as to receive ink therefrom. The roller, a is partiallyrotated while the roller, b, is in contact with it, through connectionswith the crank-shaft, d, as follows: The said roller, a carries affixedto it a ratchetwheel, 19 and an arm, b mounted loosely on the journal ofsaid roller carries a springpressed pawl, b engaging said ratchet. Ahandle, 55, is formed on said arm and a boss, b is pivoted on one sideof the arm. A rod, 1)", extends loosely through the said boss, and isconnected at its lower end with a crank, 12 on the shaft d. Said rod hasa head, If, at the upper end to abut the upper'side of the boss, I), andan adjustable collar, 12 to abut the under side of said boss. Thedownward throw of the crank, b moves the arm, b

down by reason of the engagement of the head, b, with the boss, I), andthereby the roller, a is turned; and the upward throw of the said crankmoves the said arm upward by reason of the engagement of the collar, bwith the boss, b and thereby the'pawl recovers for a new stroke. Byadjusting the collar, 12 theextent of movement of the roller isdetermined. The roller can be turned by hand when desired by moving thehandle, 11

up and down,-the boss, b, then sliding on the rod, D The amount ofpressure between rollers, a and b, may be regulated by means of thescrews, (L

The platen, e, is mounted on a vibratory support, e, pivoted at e, andis oscillated by means of atoggle-lever composed of members, a and e,the latter being connectedby a link, 6, with the crank d. The pressureis thrown on and off, 1'. e., the adjustment of the platen to operativeor inoperativeadjustment with relation to the bed, is obtained throughthe following means: The member, a, of the togglelever is mounted on aneccentric, f, to one of whose journals is affixed an arm,f. A lever, fpivoted centrally to a fixed support, has its lower end connected withthe arm,f, by a link,f and its outer or upper end proj ects at thefrontof the machine in easy reach of the operator. It will be seen thatby turning the eccentric f, the adjustment of the platen will bechanged, and when the larger side of the eccentric is forward the platenis adjusted to operate against the bed or in other words, the pressureis on, whereas when the large side of the eccentric is rearward thepressure is oif. This is clearly illustrated in Fig.2where the fulllinesshowone adjustment and the broken lines the other. These twoadjustments are effected by operating the lever, f When the latter is inits upward position the arm f, is turned down against a set-screw, fentered through a stationary lug,f and the large side of the eccentricis thrown forward. It is to be noted that under this adjustment thepoint of connection between the lever and the link at f is below a linedrawn between the pivot of said lever at f and the point of connectionbetween the link f and the arm f at f". (See Fig. 1.) The stop-screw,fis adjusted to resist the movement of the connection, f across thisline, and the parts have to be sprung somewhat to carry the connectionover. Hence, the parts will be locked in this position and cannot bedisplaced except by a downward pressure on the handle of the lever. Bysuch downward pressure the adjustment is broken and the eccentric movedto the other adjustment and the pressure is thrown off. The parts arelocked in the latter adj ustment by means of a socketed projection, g,on the lever (see Fig. 12) which engages with the round head of a screw,g, fastened in the side of the machine frame, the lever havingsufiicient resiliency to bring about engagement of these parts.

A registering or counting mechanism, h, is fastened on a horizontalbracket at the lower front part of the machine, and a lever, h,

to operate the counting mechanism. Thus the counting mechanism is onlyactuated when the pressure is on and the printing in progress.

A horizontal table, 2', is supported on brackets, 1", at the front ofthe machine and designed to hold the printed matter. A leaf, 4?, isswiveled to the said table at one corner thereof by a bolt, 1', and maybe locked in closed and open adjustment by means of a triangular frame,2' fastened to the table, and a screw, 2', fastened in the leaf, theround head of said screw adapted to be sprung over the sides of saidframe, as shown in Fig. 10. This leaf is to hold the matter to beprinted.

Fast and loose pulleys and a fly-wheel, 7', are mounted on the drivingshaft,j', of the machine, and a belt-shipper, j is pivoted to a bracket,3' on the machine frame and has an arm, j, affixed to its journal. Alever, j, is pivoted to cars on the bracket, 7' and has a slotted arm,9' engaging the arm j. A brake-shoe, 3' is aifixed to the levers pivotand arranged to bear against the periphery of the fly-wheel. The leverhas a handle, j, in easy reach of the attendant, who by operating saidlever can shift the belt and apply the brake-shoe at the same time, thusinstantly stopping the machine.

The supporting base, m, of the machine is a hollow two-part castingconnected by bolts, m and it is utilized as a store-room for therollers. The floor, m, of this room is a wooden board, 011., whose grainruns transversely of the room so as to obviate warping, and the back, mis a similarly disposed board.

Racks, m are arranged within the room to hold the rollers, and the roomis closed by a hinged door, m

The drivin -shafnj, is connected with the crank shaft, d, by gears, 0,and '0', and it is to be noted that the crank is cast in one piece withthe gear 0. The outer end of the crank journals in a bushing, 0 fastenedin a hole in the frame-casting, said hole being made large enough topermit the insertion of the crank allowing for its bend.

The oscillatory frame, p, which carries the ink-distributing rollers, b,is connected by a link, 12', with the crank, d.

It is to be observed that the collars, p and c which embrace the crank,d, are formed in tegral with the links, 19' and e, respectively, andthat the arm of the crank is reduced so as to permit of said collarsbeing slipped over the same on to the wrist of the crank.
